To all who-m it may concern:

Be it known that I, EMILE MOONEN, a citizen ofthe French -Republic, residing 69 Rue de Balagny, Paris, France, have invented certain new and useful Improvements in Roller-Bearings and Similar Antiiriction Dction.

This invention has reference to roller bearings and similar anti-friction devices, and has for its object more particularly to prevent any relative displacement of the different parts in the transverse direction, to enable the races to be madein a single piece without any joint and finally of facilitating the assemblage of such devices.

in the accompanying drawings, which object of the invention:---Figure 1 is a crosssection of a bearing of this kind with intercalary rollers. Fig. 2 is a plan view. Fig. 3 shows a bearing with interoalary balls. Fig.

4 is a cross section through the bearing dur ing its 1 age. Fig. is a par 1 plan view of a l. arrangem nt ol the bearin? t) and 7 are set nnial views Illll Mating two consljructnnml forms of the bearing according to Fig. 5.

In the constructional form in accordance with Fig. 1, the bearing comprises a ring a, the outer contour of which presents three surfaces l), c, d, forming the internal race ol the. de ice. The surfaces l), c, which are in line with each other, consti'tr the race for the rollers tire slightly fJlUJGtilllljI surl'ace d which forms part of a circular rib '6, constitutes the race on which the intcrcalary rollers 9' run. The external race is constituted by the it i of a ring comprising a groove or clntnnel i; in which a split elastic and extensible segment on. is lodged; this segment also entering the channels 1) formed the intercalary rollers g.

It will be seen in Fig. 1 that the rib e and also the extensible segment m which enters the channels 1) in the rollers j' both serve to render the rings c and j, and the various mobile parts of the device, such as the rollers ahd intercalary rollers, solid with each other, that is to say, to prevent the transverse dis- The ring is provided with a number o'l screw-threade l holes n directed. 1 di n:

manner upon a slab, table or other plane surface 0, then the rollersf and the intermediate rollers g are arranged around this ring. Upon this bearing crown is then passed the extensible segment m which has been previously sprung apart, and which is slid along until it comes opposite the different channels ,1) in the roll ers into which it enters owing to its elasticity. From this moment the ring a and mobile parts of the bearing are rendered solid one with the other in the transverse direction. The assemblage is completed by capping the bearing crown with the outer ring i', care being bad to compress the extensib e segment m by any suitable means in order that are screwed into some 01 the holes 12' in the ring j in order to press the segment inwards or tighten it until it is entirely released from the channel 7c. The ring 7' may then be withdrawn as represented in Fig. 4. The segment m and the dillerent rollers may now readily be removed in their turn.

In the constructional form shown in Fig. 3, the intermediate rollers are replaced by in torn'iediate bells g. The method of assemblage and dismountin remains the same.

. In the constructional form shown in Figs. 5 6 and 7, the arrangement is reversed, that is to say, the projecting rib e is formed on the external race, while the extensible ring m entors an appropriate groove in the inner race; these two liq-ores illustrating the application of this modified construction to a bearing with intercalary rollers in Fig. 6, and with intercalary balls in Fig. 7.

The advantages are as follo\\'s:'.lhis form of bearing insures the immobility of the several carts in the transverse direction, and there y enables all lateral stops to be dispensed with. The assemblage of roller bearings is considerably facilitated owing to the fact that the solit extensible segment, whether it be applied to the inner or to the outer race, appropriately maintains the movable elements, such as rollers or calls, which have a tendency to become disarrangod, in a temporary po..1tio.n which permits of any subsequent maniprdation for completing the assemblage. Further, it is possible to form the race in one piece without any joint.

' The invention is applicable to roller bearings and to any type of bearing of this nature.

certaine the nature of my said invention and in What manner the same is to be per formed, I declare that what I claim is:

. 1. In a roller bearing, the combination of two bearingrings, each in one piece, one of bearing-ring two integral bearing-rings, 'one of which is provided with a circular rib, and the other with a circular channel, an extensible segment lodged in said channel forming a rib on the ring, rollers having grooves engaging with the circular rib and with the segment, intermediate rolling members received in the rooves of the rollers, said channeled ring bemg provided with holes for permitting access Havin now particularly described and as to the segment whereby to compress the same when mounting or dismounting the bearings 3. In a roller bearing, the combinationof two bearing-rings, one of which is rovided with a circular rib, and the other with a citcular channel, a split extensible segment lodged in said channel forming a rib on the ring, said channeled ring having a number of screw-threaded holes formed therein to permit of compressing the extensible segment, and rollers having grooves engaging with the circular rib and with the segment.

4. In a roller bearing the combination of two bearing rings, one of which is provided with a circular rib, and the other with a circular channel, a split extensible segment lodged in said channel forming a rib on the ring, said channeled ring having a number of screw-threaded holes formed therein to permit of compressing the extensible segment, rollers havin grooves engaging with the circular rib and mediate rolling members received in the grooves of the rollers.

In testimony whereof I have hereunto placed my hand this 26th day of April 1907.
